iPhone 18 Pro Max Breaks Battery-Life Records in PCMag Lab

PCMag's lab tests crown the iPhone 18 Pro Max as the longest-lasting phone ever, recording 34 hours 31 minutes of battery life—about 2 hours more than the iPhone 17 Pro Max—thanks to a 5,567 mAh US battery and the A20 Pro's improved cooling and efficiency; the test drains the battery with active processing, radios, and a high-brightness YouTube loop. Android rivals like the Galaxy S26 Ultra and Pixel 11 Pro XL appear in the rankings but don't beat Apple, and OnePlus has signaled it will exit the US market though current models remain for sale. The Lab Award highlights standout battery performance rather than a perfect score across all metrics.
